Many of the chemicals we make today were the "tomorrows*' o f times past. Many of t h e uses for these chemicals, too, were un thought o f at the time these were first made available. Many of the users, too, are industries that were u n k n o w n a n d until o u g h t of a f e w decades ago. Tomorrow's ''tomorrows" are already part o f everything we d o and make. And what w e know . . . or are learning .. . we are ready t o share among all users and potential users o f Oldbury products.

A series of perhalogenated mono basic acids has been developed b y M. W. Kellogg to meet the growing need for surfactants that can be used effi ciently with strong acids and oxidants. The new acids are derived from chlorotrifluoroethylene and are designated Kel-F Acids. Metallic salts, esters, acid halides, alcohols, amides, nitriles, and ketones have been prepared from them. Company believes this may b e just a start on what may develop into a whole family of chlorotrifluoroethylene deriva tives. Kellogg says the new surfactants pro duce efficient emulsifying systems un der the most corrosive, high tempera ture conditions. They are characterized by high thermal stability, up to 450° F.; excellent resistance to strong acids and oxidants; selective reactivity of a carboxylic acid; surface activity in highly acidic, basic, or oxidizing media; low vapor pressure; and high density. The acids are readily miscible i n all proportions with most organic liquids; the hexanoic type is miscible with water in all proportions, but the octanoic acid has only limited solubility in water at 25° C. Kellogg says their toxicity has not yet been fully determined, and normal practices used for concentrated sulfuric acid must be considered in their use. Indicated uses, according to com pany, include promotors for two-phase reactions; additives for metal treating baths; insecticidal dispersants; gelling agents for printing inks, polishes, and lubricating greases; rubber accelera tors, antioxidants and stabilizers; and chemical intermediates.
